Constructors

constructor

new Broadphase(): Broadphase
Returns Broadphase

Properties

dirty

dirty: boolean

Set to true if the objects in the world moved.

useBoundingBoxes

useBoundingBoxes: boolean

If set to true, the broadphase uses bounding boxes for intersection tests, else it uses bounding spheres.

world

world: World

The world to search for collisions in.

Methods

aabbQuery

aabbQuery(world, aabb, result): Body[]
Returns all the bodies within the AABB.
Parameters
- world: World
- aabb: AABB
- result: Body[]
Returns Body[]

collisionPairs

collisionPairs(world, p1, p2): void
Get the collision pairs from the world
Parameters
- world: World
  The world to search in
- p1: Body[]
  Empty array to be filled with body objects
- p2: Body[]
  Empty array to be filled with body objects
Returns void

doBoundingBoxBroadphase

doBoundingBoxBroadphase(bodyA, bodyB, pairs1, pairs2): void
Check if the bounding boxes of two bodies are intersecting.
Parameters
- bodyA: Body
- bodyB: Body
- pairs1: Body[]
- pairs2: Body[]
Returns void

doBoundingSphereBroadphase

doBoundingSphereBroadphase(bodyA, bodyB, pairs1, pairs2): void
Check if the bounding spheres of two bodies are intersecting.
Parameters
- bodyA: Body
- bodyB: Body
- pairs1: Body[]
  bodyA is appended to this array if intersection
- pairs2: Body[]
  bodyB is appended to this array if intersection
Returns void

intersectionTest

intersectionTest(bodyA, bodyB, pairs1, pairs2): void
Check if the bounding volumes of two bodies intersect.
Parameters
- bodyA: Body
- bodyB: Body
- pairs1: Body[]

Returns void

makePairsUnique

makePairsUnique(pairs1, pairs2): void
Removes duplicate pairs from the pair arrays.
Parameters
- pairs1: Body[]
- pairs2: Body[]
Returns void

needBroadphaseCollision

needBroadphaseCollision(bodyA, bodyB): boolean
Check if a body pair needs to be intersection tested at all.
Parameters
- bodyA: Body
- bodyB: Body
Returns boolean

setWorld

setWorld(world): void
To be implemented by subcasses
Parameters
- world: World
Returns void

`Static` boundingSphereCheck

boundingSphereCheck(bodyA, bodyB): boolean
Check if the bounding spheres of two bodies overlap.
Parameters
- bodyA: Body
- bodyB: Body
Returns boolean
